@Grishhammer,
It is a big commitment, but it is also worth it. I didn't read them all straight through, I found it easy enough to come back and remember the main points of the previous books after reading something else.
I can't get my wife to read the books I like. I just want to share the things I love with her. I am a huge sci-fi and fantasy reader and she only likes reading non-fiction and an occasional young adult novel. What can you do.
Another series I highly recommend is the Darker Shade of Magic series by V.E. Schwab. I thought the characters had good depth and the writing wasn't repetitive.
